WOD, I haven't come across any TA indicator/ pattern that anticipate market 100% of the time. When we use any setup based on TA indicators/ patterns, we are still dealing with probabilities. Developing
proabability oriented thinking is crux of developing trader's mindset. As a human being, we don't think in probabilities and that is one of the reason why 90% people loose here.
NR7 is a simple and easy way to find out that mkt has contracted, hence expansion is eminent. You can also use Bollinger band / ATR / Standard deviation etc to get the same message.
Finally it is trader's own preference to select the toolset to read the market.
Once we have found that breakout / expansion is just around the corner, then each of us can decide how to benefit for it. As a breakout trader, we don't care for direction of breakout but have plan to trade whichever way it breaks-out. More important then that, we also know that there is something called false breakout.. and hence have plan to safegaurd us against that as well.
Check out following post , where I have mentioned about how I trade breakout. and reverse position on false breakout.

We can trade false breakout only when we have trust in our system and accept the reality of trading. Otherwise, we will be sitting and moaning about being stopped out and would have missed
a great trade signal there.
Hope this helps.
Happy Trading
